ROLL

Technical specifications

….. mm acoustic insulation rolls, made of SBR (Stirene Butadiene Rubber) fibres and granules rubber, compacted using a latex binder in a hot process. A blue synthetic, 90 g/m² non woven anti-stretch backing is applied on one side. The dimensions of the roll are: 500 cm lenght, 104 cm width including 4 cm adhesive side border for rolls overlapping during installation. The total mass surface is …..  kg/m²  and  dynamic  stiffness (s’) is MN/m³.

PTB Version: waterproof non woven anti-stretch backing for liquid screed

RADIANT Version: heat reflex textile and increased vapour barrier properties
